HIOKI 8952 DC/RMS UNIT Voltage (Wave or rectifying
out) input Amplifier
This unit is one input channel. Simply slot the 8952 into the Digital
Oscillo Series MEMORY HiCORDER 8855 for use. In addition to wave voltage
measurement, this single unit handles RMS voltage measurement. To measure high
voltages, this unit comes equipped with a Power terminal for the DIFFERENTIAL
PROBE 9322. It can also be connected directly to each channel.
